In response to Re: shallow well pump problems
A 15 amp breaker is probably adequate for a 20 - 40 pump, but the breaker tripping at 30 psi indicates that the pressure regulator is telling the pump to start at 30 rather than 20. No big deal actually, but the total electrical amperage demand is what is tripping the breaker. That indicates either that the pump motor is trying to start while there is still too much pressure against the impeller, or else that the brushes or windings in the electric motor are leaking current, and causing increased amperage draw (more than the allowable 15 amps). It isn't likely its the breaker, or a pressure problem but more likely a motor issue. Not knowing how much of a semi-amateur you are, you might be able to replace both the pump and motor, but there are many, many variables. First, is there a valve between the tank and the pump to prevent the storage tank from draining? If not are you capable of plumbing one in? If not, you would be better advised to contact a LICENSED plumber to do the job for you professionally.

: My shallow well pump has been acting up lately, but I'm not sure what the problem is. Occasionally, it will trip the circuit breaker (15 amp) when it gets to around 30 pounds pressure on the tank. The pump is a 20-40. Yesterday, it happened four times, and it's happened once so far today. When I reset the breaker, it works as normal. I did catch it once in the act and the pump motor didn't feel hot after it kicked the breaker. Is it the breaker, impeller, motor, dirt or gravel? (although we never have had a problem with dirty water or gravel in the lines) Any ideas? Also, how easy is it for a semi-amateur like myself to replace the pump. It doesn't look that complicated, but doesn't the storage tank need to be re-pressurized once the new pump is installed?
